Batch¶
The purpose of this sub-command is to facilitate job submission on
clusters that use SLURM as their workload manager. Note that this tools
assumes that the SLURM file is properly prepared by the user and does
not modify the SLURM script in any way. Similar to other sub-commands
batch
has several sub-commands itself:
cms batch create-job JOB_NAME --slurm-script=SLURM_SCRIPT_PATH \
--input-type=INPUT_TYPE --slurm-cluster=SLURM_CLUSTER_NAME \
--job-script-path=SCRIPT_PATH --remote-path=REMOTE_PATH \
--local-path=LOCAL_PATH [--argfile-path=ARGUMENT_FILE_PATH] \
[--outfile-name=OUTPUT_FILE_NAME] [--suffix=SUFFIX] [--overwrite]
cms batch run-job JOB_NAME
cms batch fetch JOB_NAME
cms batch test-connection SLURM_CLUSTER_NAME
cms batch set-param slurm-cluster CLUSTER_NAME PARAMETER VALUE
cms batch set-param job-metadata JOB_NAME PARAMETER VALUE
cms batch list slurm-clusters [DEPTH [default:1]]
cms batch list jobs [DEPTH [default:1]]
cms batch remove slurm-cluster CLUSTER_NAME
cms batch remove job JOB_NAME
cms batch clean-remote JOB_NAME
The main options are:
create-job
: used for creating a job configuration (this does not run the job automatically)run-job
: used for running a job configuration that is previously created.test-connection
: used for testing the connection to a SLURM clusterset-param
: used for setting a parameter in any configuration keylist
: used for listing possible instances of an entityremove
: used for removing a cluster or jobclean-remote
: used for cleaning the files of a job from a cluster
Each of these sub-commands are reviewed in the following sections with examples.
Creating a job configuration¶
As can be seen, this sub-command has the most number of arguments and is
the vital part of the batch
tool. The parameters are all
self-explanatory, but we will review the important ones here:
--slurm-script
: defines the path to the SLURM script that is going to be submitted to the SLURM cluster.--input-type
: defines the type of input for the application that is going to be run on the cluster. This is important because if the program takes a file name as an argument, that file has to be transferred to the cluster as well. Possible values for this parameter is eitherparams
orparams+file
. Note that if you passparams+file
then you have to specify the--argfile-path
as well where you define the path to the argument file.--slurm-cluster
: defines the name of the cluster that is previously defined in cloudmesh yaml file.--job-script-path
: defines the path to the file that is going to be run on the SLURM cluster--remote-path
: defines the path on SLURM cluster on which the job files are going to be copied, run and collected.--local-path
: defines the local path for saving the results.
Consider the following example :
cms batch create-job SlurmTest1 --slurm-script=./1_argsin_stdout.slurm \
--input-type=params --slurm-cluster=slurm-taito \
--job-script-path=./1_argsin_stdout_script.sh \
--remote-path=~/tmp --local-path=../batch/sample_scripts/out \
--overwrite
This will create a job that looks like this in the slurm_batch
configuration file placed in the workspace directory:
slurm_cluster:
slurm-taito:
name: taito
credentials:
sshconfigpath: ~/vms/sshconfig_slurm
job-metadata:
SlurmTest1:
suffix: _20181206_19275141
slurm_cluster_name: slurm-taito
input_type: params+file
raw_remote_path: ~/tmp
slurm_script_path: ./4_filein_fileout.slurm
job_script_path: ./4_filein_fileout_script.sh
argfile_path: ./test-script-argument
argfile_name: test-script-argument
script_name: 4_filein_fileout_script.sh
slurm_script_name: 4_filein_fileout.slurm
remote_path: ~/tmp/job_20181206_19275141/
remote_script_path: ~/tmp/job_20181206_19275141/4_filein_fileout_script.sh
remote_slurm_script_path: ~/tmp/job_20181206_19275141/4_filein_fileout.slurm
local_path: ../batch/sample_scripts/out
Testing the connection¶
Note that the cluster information is already extracted and added to this
file. Therefore unlike vcluster
, there is no need to add the cluster
manually. So far, we have just added and updated the configuration and
the job is neither submitted nor run in the cluster. Before doing that,
let’s try to test our connection to the cluster:
cms batch test-connection slurm-taito
# Slurm Cluster taito is accessible.
Running the Job¶
Now that we are sure that the ssh connection works fine, let’s try to run the job:
cms batch run-job SlurmTest1
# Remote job ID: 32846209
Despite the short output, this command does a lot of work behind the seen including:
Creating the proper folder structure in the remote
Copying the SLURM script, as well as the job script and the argument files if any.
Submitting the job
Keeping the job ID and save it in the configuration file so that the results can be fetched later
Just for the demonstration purpose, let’s check the remote folder in the cluster and you will see that all of the files as well as the results will be available there:
taito-login3:~/tmp/job_20181206_19301175$ ll
total 28
drwxr-xr-x 2 4096 Dec 7 02:36 ./
drwx------ 3 4096 Dec 7 02:35 ../
-rwxr-xr-x 1 238 Dec 7 02:35 4_filein_fileout.slurm*
-rw-r--r-- 1 0 Dec 7 02:36 4_filein_fileout.slurm.e32846209
-rw-r--r-- 1 117 Dec 7 02:36 4_filein_fileout.slurm.o32846209
-rwxr-xr-x 1 48 Dec 7 02:35 4_filein_fileout_script.sh*
-rw-r--r-- 1 35 Dec 7 02:35 test-script-argument
-rw------- 1 35 Dec 7 02:36 test-script-output
Downloading the Results¶
Now that the results are ready we can fetch the results using the following command:
cms batch fetch SlurmTest1
collecting results
Results collected from taito for jobID 32846209
waiting for other results if any...
All of the remote results collected.
Using this, the results will be downloaded in the local path specified in the configuration file:
out$ ll job_20181206_19301175/
total 1M
drwxr-xr-x 2 corriel 1M Dec 6 19:40 ./
drwxr-xr-x 3 corriel 1M Dec 6 19:40 ../
-rw-r--r-- 1 corriel 0M Dec 6 19:40 4_filein_fileout.slurm.e32846209
-rw-r--r-- 1 corriel 1M Dec 6 19:40 4_filein_fileout.slurm.o32846209
-rw------- 1 corriel 1M Dec 6 19:40 test-script-output
Cleaning the remote¶
Now that you are done, you can easily clean the remote using:
cms batch clean-remote SlurmTest1
Job SlurmTest1 cleaned successfully.
Get the list of the jobs and clusters¶
Naturally after working with the batch
for a while, several jobs and
clusters will be accumulated in the configuration file. You can get the
list of current jobs and clusters using the following commands:
cms batch list slurm-clusters
slurm-taito:
name
credentials
cms batch list jobs
SlurmTest1:
suffix
slurm_cluster_name
input_type
raw_remote_path
slurm_script_path
job_script_path
argfile_path
argfile_name
script_name
slurm_script_name
remote_path
remote_script_path
remote_slurm_script_path
local_path
jobIDs
It is also possible to increase the depth of the information by adding the desired depth as the next parameter:
cms batch list slurm-clusters 2
slurm-taito:
name:
taito
credentials:
sshconfigpath:
~/vms/sshconfig_slurm
Modifying the Configuration by Setting Parameters¶
In case you want to modify or add a configuration parameter, there is no
need to directly modify the file. Indeed you can use the set-param
command to set a key for both jobs and slurm-clusters. In the next
example we will add a test-key and test-value parameter to the
slurm-taito
cluster:
cms batch set-param slurm-cluster slurm-taito test-key test-value
slurm-cluster parameter test-key set to test-value successfully.
cms batch list slurm-clusters 2
slurm-taito:
name:
taito
credentials:
sshconfigpath:
~/vms/sshconfig_slurm
test-key:
test-value
Removing jobs and clusters¶
Finally, when you are done with a job, or when a cluster is not
accessible anymore, you can easily remove them from the batch
configuration file using the following:
cms baremove slurm-cluster slurm-taito
Slurm-cluster slurm-taito removed successfully.
Similarly, you can remove a obsolete job using the following command:
cms batch remove job SlurmTest1
Job SlurmTest1 removed successfully.

Community at risk due to uncontrolled fire in state’s North
An uncontrolled blaze is threatening a remote beachside community in the state’s North.
An investigation is underway to determine the cause of a 250ha fire placing the small coastal community of Lulworth at risk.
Sixty crews were tackling the blaze on Sunday afternoon, including five aircraft.
TFS regional chief North Ian Bounds said.
“Investigations will continue through Monday, but at this stage it’s not believed to have started by natural causes,” he said.
Mr Bounds said the fire, now at Watch and Act level, was proving difficult for crews to control.
He said people should stay away from the Lulworth area while crews worked to contain the blaze.

EARLIER: AN uncontrolled fire raging in the state’s North is placing the small coastal community of Lulworth at risk.
At 8pm, Tasmania Fire Service warned that the Maitland Bay vegetation fire would put Lulworth and nearby Tam O’Shanter Bay at high risk.
Residents are reminded that embers, smoke and ash falling on the town and bay could threaten houses earlier than the main fire.
The TFS advise that if your home is well prepared and actively defended, it could provide shelter. But if your family has a bushfire survival plan, to use it now.
There is no evacuation centre near the fire at the moment.

In this step, you will learn how to create a layout template and how to build an app that has multiple views by adding routing.
Note that when you now navigate to app/index.html
, you are redirected to app/index.html#/phones
and the same phone list appears in the browser. When you click on a phone link the stub of a phone
detail page is displayed.
The most important changes are listed below. You can see the full diff on GitHub:
Our app is slowly growing and becoming more complex. Before step 7, the app provided our users with
a single view (the list of all phones), and all of the template code was located in the
index.html
file. The next step in building the app is to add a view that will show detailed
information about each of the devices in our list.
To add the detailed view, we could expand the index.html
file to contain template code for both
views, but that would get messy very quickly. Instead, we are going to turn the index.html
template into what we call a "layout template". This is a template that is common for all views in
our application. Other "partial templates" are then included into this layout template depending on
the current "route" — the view that is currently displayed to the user.
Application routes in angular are declared via the
$routeProvider
, which is the provider of the
$route service
. This service makes it easy to wire together
controllers, view templates, and the current
URL location in the browser. Using this feature we can implement deep linking, which lets us utilize the browser's
history (back and forward navigation) and bookmarks.
As you noticed the dependency injection is the core feature of AngularJS, so it's important for you to understand a thing or two about how it works.
When the application bootstraps, Angular creates an injector that will be used for all DI stuff in
this app. The injector itself doesn't know anything about what $http
or $route
services do, in
fact it doesn't even know about the existence of these services unless it is configured with proper
module definitions. The sole responsibilities of the injector are to load specified module
definition(s), register all service providers defined in these modules and when asked inject
a specified function with dependencies (services) that it lazily instantiates via their providers.
Providers are objects that provide (create) instances of services and expose configuration apis
that can be used to control the creation and runtime behavior of a service. In case of the $route
service, the $routeProvider
exposes apis that allow you to define routes for your application.
Angular modules solve the problem of removing global state from the application and provide a way of configuring the injector. As opposed to AMD or require.js modules, Angular modules don't try to solve the problem of script load ordering or lazy script fetching. These goals are orthogonal and both module systems can live side by side and fulfil their goals.
app/js/app.js
:
angular.module('phonecat', []). config(['$routeProvider', function($routeProvider) { $routeProvider. when('/phones', {template: 'partials/phone-list.html', controller: PhoneListCtrl}). when('/phones/:phoneId', {template: 'partials/phone-detail.html', controller: PhoneDetailCtrl}). otherwise({redirectTo: '/phones'}); }]);
In order to configure our application with routes, we need to create a module for our application.
We call this module phonecatApp
and using the config
api we request the $routeProvider
to be
injected into our config function and use $routeProvider.when
api to define our routes.
Note that during the injector configuration phase, the providers can be injected as well, but they will not be available for injection once the injector is created and starts creating service instances.
Our application routes were defined as follows:
The phone list view will be shown when the URL hash fragment is /phones
. To construct this
view, Angular will use the phone-list.html
template and the PhoneListCtrl
controller.
The phone details view will be shown when the URL hash fragment matches '/phone/:phoneId', where
:phoneId
is a variable part of the URL. To construct the phone details view, angular will use the
phone-detail.html
template and the PhoneDetailCtrl
controller.
We reused the PhoneListCtrl
controller that we constructed in previous steps and we added a new,
empty PhoneDetailCtrl
controller to the app/js/controllers.js
file for the phone details view.
The statement $route.otherwise({redirectTo: '/phones'})
triggers a redirection to /phones
when
the browser address doesn't match either of our routes.
Note the use of the :phoneId
parameter in the second route declaration. The $route
service uses
the route declaration — '/phones/:phoneId'
— as a template that is matched against the current
URL. All variables defined with the :
notation are extracted into the
$routeParams
object.
In order for our application to bootstrap with our newly created module we'll also need to specify
the module name as the value of the ngApp
directive:
app/index.html
:
<!doctype html>  ...
app/js/controller.js
:
... function PhoneDetailCtrl($scope, $routeParams) { $scope.phoneId = $routeParams.phoneId; } //PhoneDetailCtrl.$inject = ['$scope', '$routeParams'];
The $route
service is usually used in conjunction with the ngView
directive. The role of the ngView
directive is to include the view template for the current
route into the layout template, which makes it a perfect fit for our index.html
template.
app/index.html
:
  ...

Note that we removed most of the code in the index.html
template and replaced it with a single
line containing a div with ng-view
attribute. The code that we removed was placed into the
phone-list.html
template:
app/partials/phone-list.html
:

  Search: <input ng-model="query"> Sort by: <select ng-model="orderProp"> <option value="name">Alphabetical</option> <option value="age">Newest</option> </select>

  {{phone.name}}
{{phone.snippet}}

We also added a placeholder template for the phone details view:
app/partials/phone-detail.html
:
TBD: detail view for {{phoneId}}
Note how we are using phoneId
model defined in the PhoneDetailCtrl
controller.
To automatically verify that everything is wired properly, we wrote end-to-end tests that navigate to various URLs and verify that the correct view was rendered.
... it('should redirect index.html to index.html#/phones', function() { browser().navigateTo('../../app/index.html'); expect(browser().location().url()).toBe('/phones'); }); ... describe('Phone detail view', function() { beforeEach(function() { browser().navigateTo('../../app/index.html#/phones/nexus-s'); }); it('should display placeholder page with phoneId', function() { expect(binding('phoneId')).toBe('nexus-s'); }); });
You can now refresh the browser tab with the end-to-end test runner to see the tests run, or you can see them running on angular's server.
{{orderProp}}
binding to index.html
, and you'll see that nothing happens even
when you are in the phone list view. This is because the orderProp
model is visible only in the
scope managed by PhoneListCtrl
, which is associated with the

element. If you add
the same binding into the phone-list.html
template, the binding will work as expected.With the routing set up and the phone list view implemented, we're ready to go to step 8 to implement the phone details view.


Computer generates random 4 digit number
Your task is to guess it, and every guess will provide you with following information:
- Every digit which was placed correctly marked as 'B'
- Every digit which was not placed correctly, but present in the number marked as 'K'
- Every digit which is not in the number marked as '.'
After number was guessed guessing again will restart the game


Over the course of the past two months, I, along with two others, have developed a musical interface from scratch, using commonly available parts and software tools. We started by brainstorming with simple notes and ideas, and ended with a fully fledged prototype that we performed with in front of our class and lecturers. I have been keeping a blog throughout this whole process, which describes each of the stages in greater detail (a complete list of posts available here), but in this post I will wrap up what we did, as a rounded conclusion to the project.
Coming up with Waves To Waves
As I said in the opening paragraph, we started with nothing - coming together with a stack of Post-It notes and a small amount of time to fire out ideas to each other. We all knew that we wanted to do a musically-oriented project due to our respective musically-involved backgrounds and interests, but that was it. We started with ~30 ideas, ranging from the feasible to the comparatively ridiculous - but at that stage, no idea was a bad idea, as all steps helped to bring us closer to the final topic. Eventually, we narrowed it down to around four primary ideas, ranging from a tangible speaker that you physically manipulate to alter the sound, to a three-dimensional laser based instrument that uses fog as an interactive medium. However, we all settled on the concept of a “water-based musical interface”, a small handful of words that would eventually turn into Waves To Waves (WTW).
Once we had one idea, we set about refining it, narrowing down the scope so that we could specifically say what parts we needed, and how we would build it. This wasn’t a one-time process, as our first final idea candidate was notably different to what we ended up with - starting with a row of buoyant balls that are tracked by a Kinect as they bob up and down on the water as the surface is disturbed.
WTW as it is today came about after discussions with Pete Bennett and Paul Worgan, who are researchers in the University of Bristol BIG lab with an active interest in musical interfaces. We initially pitched WTW as a large installation with a strong expressive performance element and a strong mathematical foundation (that literally turned physical waves into sound waves via a one-to-one mapping), but Pete and Paul recommended that we go down a more user-friendly, collaborative route. Taking on board their advice, we down-scaled WTW to something that could “fit in a backpack” (it can), and placed the focus more around ease of use and a pleasing audible result, instead of an accurate mathematical simulation of wave mechanics.
Developing the prototype
By this point in the design process, we knew actually what we _wanted _to build. It was just a matter of building it. Before starting however, we needed to gain more experience with the tools we aimed to use, and so each of us spent a week learning how to use the Arduino, and how to use Pure Data. This was a valuable step as it allowed us to step ahead more wisely by knowing the advantages and the pitfalls of the tools we were using.
WTW purposefully has a very simple and cheap construction. The “water tank” is a storage container bought from Wilkinsons, the sensors were bought for ~£4 a piece off eBay, and the wooden frame was constructed from some wood sitting in the garden of my student house. Also, a friend of ours, Tom Mortensson, kindly allowed us to borrow some of his 3-pin cables for hooking up the sensors to the Arduino, as well as a sensor shield for making interfacing more of a plug-and-play operation. Nonetheless, the final product comes together quite well, and proves how you don’t have to have a large budget to build a functioning musical interface.

Preparing the performance
Since we had what was basically a complete product (in a physical sense) by the start of December, we looked towards preparing a performance, and tweaking WTW so that it functioned better within a live environment. We experimented with playing it collaboratively with other instruments. We experimented with different musical styles and sounds. Essentially, we strove to explore what water lent itself best to as a transmissive medium for a musical instrument.
We found that due to the lack of precision of both the movement capabilities of water, and the inexpensive water depth sensors we had purchased, WTW wasn’t suited to fill the role of an instrument designed to play a melodic line. Instead, similarly to Kugelschwung (an older project of mine that also used a cumbersome mechanic for generating music), we decided to have WTW generate ambient soundscapes that played more of a supportive role in a wider musical arrangement. Therefore, for the debut musical performance, we employed two keyboard synthesisers to create a fully-textured musical performance.
Footage of this debut performance (embedded in the previous Interactive Devices post) is available here.
Preparing the paper and video
Despite having scope for six pages, we found the CHI paper layout to be relatively restrictive in terms of how much we could actually include, and so we had to be rather selective in what we included in the paper. Thus, we thought it was primarily important to include these sections:
- An introduction to the project
- A brief review of previous articles of related academic literature
- An overview of the hardware and software behind Waves To Waves
- A discussion on how it fits within the wider HCI community
- A discussion on how Waves To Waves could be expanded to further our concepts
While the paper does a good job of describing the past, present and future of Waves To Waves, it doesn’t show it in action - and so this is where the affiliated video fills a valuable gap. We aimed to make the video as approachable as possible, by presenting it in a similar style to how we presented the interface to peers and lecturers on the 10th of December. Below is said demonstration video:
Thoughts on how we did as a group
Before the project, James, Ben and I were all good friends, and so working together was painless since we already knew what each of our skills and preferences were, and since we felt we could be completely honest with each other during design discussions. Furthermore, despite initially feeling at a disadvantage, we felt that working in a three was actually preferable to working in a larger group (the average group size was five), since there was less of an overhead from team management, and less conflict from design disputes. We kept a very agile working form, kept constant communication, and ensured that each of us had a job to do - where progress was constantly and immediately reported. Moreover, we met and worked together regularly - as our smaller group size meant that collectively we were more flexible in terms of how we worked.
In terms of our performance as a group I have no regrets or criticisms. All members of the team pulled their weight equally, and all added valuable contributions which pushed the project forward. I took the lead on the software that sat between the interface and the proprietary synthesiser that generated the sound, James took the lead on the video, and Ben took the lead on the paper - with each of us contributing in all areas to varying degrees.
Final words
My parting word on this project is that it truly has been a lot of fun - in a world of strict assignments and theoretical rigidity, it was refreshing to get free rein to make something I actually wanted to make, employing my existing technical and musical knowledge. Since I’m very interested in musical interfaces, and indeed music itself, I feel that I learned more in this assignment by exploring technologies and methods in my own time than I would have by reading a textbook or a series of papers on topics I care little for. Thus, I would heartily recommend this unit to any current third year Computer Science students at Bristol, especially if you’re creatively minded. It’s a rare opportunity to put a little of yourself into the work.

Buying foreign instead of local rice 'insensetive'
by Marlon PurificacionSENATOR Imee Marcos has denounced the plan of the Philippine International Trading Corporation to import rice in behalf of local fastfood chains, grocery stores, and small supermarkets.
Marcos expressed dismay that a government-owned corporation under the Department of Trade and Industry (DTI) would prioritize imports over local produce when rice farmers nationwide have been selling their harvest at depressed prices or even at a loss.
“The announcement of Secretary (Ramon) Lopez is insensitive and ill-timed. Cheaper imported rice is not worth a breakdown in the livelihood of Filipino rice farmers,” Marcos said.
The DTI chief announced the plan to import rice for select businesses at an international rice conference in Makati earlier this week and also said that as many as 300 containers could be shipped to the country in the next few months.
“Where is our conscience and what got into the heads of these businessmen who choose foreign goods over our very own at a time of crisis?” Marcos asked.
“Have pity on our rice farmers who could hardly make a living. Just drop it!” Marcos fumed.

I’m A Celebrity viewers express concern for Dec Donnelly as they spot second injury
He sported another injury earlier this week
by Rebecca CarterViewers of I'm A Celebrity spotted host Dec Donnelly was sporting a second injury during last night's episode.
During Sunday night's launch, the presenter had a burn on his arm and he explained to worried fans that his injury was caused when he burnt himself while sterilising daughter Isla’s dummies.
On last night's episode, Dec was wearing a plaster on his finger and it got some fans talking.
 We worry!!!!"
Dec replied: "So accident prone atm! D."
Another wrote: "What’s happened to Decs finger? Bless always seems injured. What’s Australia doing to you Dec."
A third tweeted: "Which finger? He had a bandaid on his left (?) index finger for the launch show, I think. Might still be a blister from his encounter with boiling water."

It comes after viewers asked about Dec's burn on his arm.
One fan had tweeted during the episode: "Dec - what have you done to your arm? Looks like a nasty injury."
Dec replied: "Nothing exciting unfortunately. I scalded myself while sterilising Isla’s dummies!"
Meanwhile, during last night's show, two new campmates were revealed - Andy Whyment and Cliff Parisi.
Call The Midwife star Cliff said in a VT: "[The campmates] are all mates now and I'm going to come in and they're going to be like, 'go away.' Come on you spiders! Come on your crocodiles!"
Read more: I'm A Celebrity viewers elated as Cliff Parisi and Andy Whyment announced as new campmates
Andy, who plays Kirk Sutherland in Coronation Street, said: "I've got absolutely no survival skills.
"I don't think I do have any fears or phobias but watch me now when I get in there... I'm going to be [bleep] scared of everything."
I'm A Celebrity continues tonight at 9pm on ITV.

Bayelsa election: PDP splits over Jonathan's role in poll
- PDP chieftains in Bayelsa are divided over the role of former President Goodluck Jonathan in the just concluded governorship election in the state
- Some PDP chieftains in Bayelsa say Jonathan should not be blamed for the defeat of their party
- Others believe that the former president should be held responsible for the ruling party
A report by The Nation indicates that the role played by former President Goodluck Jonathan to back the All Progressives Congress (APC) and help influence their victory at the just concluded governorship election in Bayelsa has divided the Peoples Democratic Party (PDP) in the state.
While some PDP chieftains in Bayelsa say Jonathan should not be blamed for the defeat of their party, others believe that the former president should be held responsible for the ruling party's defeat.
Other party leaders, however, said that the alleged selfishness and autocratic leadership style of the state governor, Seriake Dickson, compelled Jonathan to take a back seat in the affairs of the PDP before and during the election.
A party leader, who spoke under the condition of anonymity said: “Nobody should mention Jonathan’s name. We were all witnesses when Dickson and some of his co-travelers vowed to retire Jonathan from politics. Dickson took all decisions alone.
“In the 2019 general election, Dickson singlehandedly selected all the PDP candidates that contested the National and House of Assembly elections including in the constituencies of Jonathan.
“When it came to the last governorship election, Dickson sidelined Jonathan even when Jonathan brought many senior citizens in the PDP to beg him to allow a former Managing Director, Niger Delta Development Commission (NDDC), Chief Timi Alaibe, to fly the flag of the PDP. Dickson refused. He was arrogant.
“He went ahead to impose his preferred candidate on the people and organised a stage-managed primary to actualise his wish. As if Dickson was not done, he ignored all entreaties by different stakeholders to give the running mate slot to anybody from Jonathan’s local government area.

He said that as at the time Dickson made moves for reconciliation, the damage had been done as most foot soldiers of Jonathan and Alaibe had already left the PDP.

But an aide to the governor said there was no reason for Jonathan to have abandoned the PDP the way he did before and during the governorship election, adding that his decision to stay away from the activities of the party led to the loss of Bayelsa to APC.
The source said there was no sin Dickson allegedly committed that should not have been forgiven by Jonathan.
“In the interest of the PDP, Jonathan should have overlooked the errors of Dickson and work for the PDP to win the election. His absence was felt by the people of Bayelsa and his body language suggested that he wanted the opposition to win.

“We can now see that he supported the candidate of the opposition. What the former president did was anti-party,” he said.
Meanwhile, the deputy national publicity secretary of the APC, Mr Yekini Nabena has berated Governor Dickson for claiming that security agencies helped the party win the Bayelsa governorship election.
Nabena who dismissed the claims by the governor urged Nigerians to disregard the claim and not take Governor Dickson's statement seriously.
According to him, the election was free and fair and it was obvious that the people of Bayelsa state chose to embrace change.

The M_time(3f) Fortran module and associated utility programs provide date and time-related procedures. Both a procedural and OOP (Object Oriented Programming) interface are provided. Each routine is accompanied by a man-page which includes a sample program for that procedure. This manual, the source and example utility programs are included in the download.
The M_time(3f) module
The M_TIME(3f) module complements the DATE_AND_TIME(3f) procedure, which is the standard intrinsic subroutine that returns the current date and time in the Gregorian calendar. That is, the primary way this module represents dates is as an integer array with the same meaning for elements as defined by the DATE_AND_TIME(3f) routine. In addition it can calculate or read many other date representations such as ...
Julian and Unix Epoch Dates are particularly useful for manipulating dates in simple numeric expressions.
The extensive formatting options include showing SYSTEM_CLOCK(3f) and CPU_USAGE(3f) information along with Gregorian date information, allowing for the easy incorporation of timing information into program messages. In addition to conventional Civilian Calendar dates, the module supports the ISO-8601 standard methods of displaying dates.
A Fortran-callable sleep(3c)/usleep(3c) procedure is also provided.

FMTDATE
You can easily use Julian Ephemeris Dates and Unix Epoch Times to add and subtract times from dates or to calculate the interval between dates. But JEDs and UETs and even the Gregorian Calendar arrays in the DAT arrays are not the way we typically describe a date on the Civilian Calendar. So the fmtdate(3f) routine lets us print a DAT array in a variety of familiar styles.
The fmtdate(3f) and now(3f) procedures let you display a Gregorian date using either keywords for standard formats or using macros in a user-specified formatting string. A formatting string may contain the following macros:
Description Example Base time array: (1) %Y -- year, yyyy 2016 (2) %M -- month of year, 01 to 12 07 (3) %D -- day of month, 01 to 31 27 %d -- day of month, with suffix (1st, 2nd,...) 27th (4) %Z -- minutes from UTC -0240 %z -- -+hh:mm from UTC -04:00 %T -- -+hhmm from UTC -0400 (5) %h -- hours, 00 to 23 21 %H -- hour (1 to 12, or twelve-hour clock) 09 %N -- midnight< AM <=noon; noon<= PM <midnight PM (6) %m -- minutes, 00 to 59 24 (7) %s -- sec, 00 to 59 22 (8) %x -- milliseconds 000 to 999 512 Conversions: %E -- Unix Epoch time<PHONE_NUMBER>.5129952 %e -- integer value of Unix Epoch time<PHONE_NUMBER> %J -- Julian date 2457597.559 %j -- integer value of Julian Date(Julian Day) 2457597 %O -- Ordinal day (day of year) 209 %o -- whole days since Unix Epoch date 17009 %U -- day of week, 1..7 Sunday=1 4 %u -- day of week, 1..7 Monday=1 3 %i -- ISO week of year 1..53 30 %I -- iso-8601 week-numbering date(yyyy-Www-d) 2016-W30-3 Names: %l -- abbreviated month name Jul %L -- full month name July %w -- first three characters of weekday Wed %W -- weekday name Wednesday %p -- phase of moon New %P -- percent of way from new to full moon -1% Literals: %% -- a literal % % %t -- tab character %b -- blank character %B -- exclamation(bang) character %n -- new line (system dependent) %q -- single quote (apostrophe) %Q -- double quote Program timing: %c -- CPU_TIME(3f) output .78125000000000000E-001 %C -- number of times this routine is used 1 %S -- seconds since last use of this format .0000000000000000 %k -- time in seconds from SYSTEM_CLOCK(3f) 588272.750 %K -- time in clicks from SYSTEM_CLOCK(3f) 588272750 If no percent (%) is found in the format one of several alternate substitutions occurs. If the format is composed entirely of one of the following keywords the following substitution occurs: "iso-8601", "iso" ==> %Y-%M-%DT%h:%m:%s%z ! Example: 2017-08-26T18:56:33,510912700-04:00 "iso-8601W", "isoweek" ==> %I "sql" ==> "%Y-%M-%D %h:%m:%s.%x" "sqlday" ==> "%Y-%M-%D" "sqltime" ==> "%h:%m:%s.%x" "rfc-2822" ==> %w, %D %l %Y %h:%m:%s %T ! Example: Mon, 14 Aug 2006 02:34:56 -0600 "rfc-3339" ==> %Y-%M-%DT%h:%m:%s%z ! Example: 2006-08-14 02:34:56-06:00 "date" ==> %w %l %D %h:%m:%s UTC%z %Y "short" ==> %w, %l %d, %Y %H:%m:%s %N UTC%z "long"," " ==> %W, %L %d, %Y %H:%m:%s %N UTC%z "suffix" ==> %Y%D%M%h%m%s "formal" ==> The %d of %L %Y "lord" ==> the %d day of %L in the year of our Lord %Y "easter" ==> FOR THE YEAR OF THE CURRENT DATE: Easter day: the %d day of %L in the year of our Lord %Y "all" ==> A SAMPLE OF DATE FORMATS otherwise the following words are replaced with the most common macros: String Macro Example year %Y 2016 month %M 07 MONTH %L July Month %l Jul day %D 27 DAY %d 7th hour %h 21 HOUR %H 10 GOOD %N AM minute %m 24 second %s 22 weekday %u 3 Weekday %w Thu WEEKDAY %W Thursday timezone %T -0400 Timezone %Z -240 TIMEZONE %z -04:00 epoch %e<PHONE_NUMBER> julian %j 2457597 ordinal %O 209 if none of these keywords are found then every letter that is a macro is assumed to have an implied percent in front of it. For example: YMDhms ==> %Y%M%D%h%m%s ==><PHONE_NUMBER>2422
If you prefer an Object-oriented interface the M_time__oop module (included with the M_time module source) provides an OOP interface to the M_time module.
The following example program demonstrates the extensive options available for formatting a date as well as how to use the module to calculate dates such as "Yesterday" and "Tomorrow".

A "date_and_time" array "DAT" has the same format as the array of values generated by the Fortran intrinsic DATE_AND_TIME(3f). That is, it is an 8-element integer array containing year, month, day, Time zone difference from UTC in minutes, hour, minutes, seconds, and milliseconds of the second. This array represents a date on the Proleptic Gregorian Calendar.
The Proleptic Gregorian Calendar assumes the Gregorian Calendar existed back to the beginning of the Julian Day calendar (4713 BC). This means historic dates will often be confused, as the Julian Calendar was used in the USA until 1752-09-03, for example. The Gregorian Calendar was formally decreed on 1582-10-15 but was not adapted in many countries. The Julian Calendar was first used around 45 BC. Note that the Proleptic Gregorian Calendar includes a year zero (0). It is frequently used in computer software to simplify the handling of older dates. For example, it is the calendar used by MySQL, SQLite, PHP, CIM, Delphi, Python and COBOL. The Proleptic Gregorian Calendar is explicitly required for all dates before 1582 by ISO 8601:2004 (clause <IP_ADDRESS> The Gregorian calendar) if the partners to information exchange agree.Unix Epoch Time (UET) is defined as the number of seconds since 00:00:00 on January 1st. 1970, UTC.
A JED is defined as a Julian Ephemeris Date. JED days start at noon (not at midnight). 4713-01-01 BC at noon is defined as JED 0.0.
If you are not familiar with them, in this context Julian Dates and Unix Epoch Times are scalar numbers that allow for easy computations using dates (to go back one day just subtract one from a Julian Date, for example). Since these values are generally not considered intelligible, routines are included to convert between these scalar values and the date array so human-readable results can be obtained.
Coordinated Universal Time (French: Temps universel coordonn'e), abbreviated as UTC, is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0o longitude;[1] it does not observe daylight saving time. It is one of several closely related successors to Greenwich Mean Time (GMT). For most purposes, UTC is considered interchangeable with GMT, but GMT is no longer precisely defined by the scientific community.
Like most collections of date and time procedures M_time is not a high-precision library that accounts internally for leap seconds and relativistic effects.
M_time(3f) is intended for use in the recent era and is not appropriate for use with historical dates that used some other calendar scheme such as the Julian Calendar. That is, you have to remember to account for conversions to other calendar systems when using historical dates.
When Daylight Savings is in effect calculations will generally be correct, as the date model includes a timezone value; but you are responsible for ensuring dates you create use the correct timezone value or otherwise account for Daylight Savings Time as needed.
Currently, dates are manipulated using the current system timezone, which can typically be set using the environment variable TZ. So if you desire to set the default timezone you generally set the environment variable before executing your program. This is compatible with current observed behavior for the intrinsic procedure DATE_AND_TIME(3f) with compilers I have tested with, but does not seem to be a specified behavior as far as the standard is concerned. That is, DATE_AND_TIME(3f) returns a vector that contains a current time zone, but does not specify how a current time zone can be explicitly set. Since this library is intentionally designed to complement DATE_AND_TIME(3f) it adopts the same behavior. A routine to let you set a default time zone could be added in the future.
Note the environment variable can be set using put_environment_variable(3f) from the libGPF library:
use M_system, only : put_environment_variable call put_environment_variable('TZ','America/New_York',ierr)
The ISO-8601 standard is often used for business-related transactions.
There are (of course) the C/C++ intrinsics which provide much of the same functionality that should be bindable to Fortran via the ISO_C_BINDING module.
If you are looking for a high-precision Fortran library that is well tested for manipulating dates I would suggest looking at the NASA SPICElib library. If you care about Leap Seconds, Orbital Mechanics, GPS/Satellite communications, and Astronomy it is worth a look.
The Fortran Wiki fortranwiki.org contains information on other libraries and modules that provide date-time procedures.

My path to finding GIS first started with a childhood interest in maps that was expanded by my discovery of the subject of geography my first year at college. After seeing the urban vibrancy of Barcelona during a winter break trip, I became interested in the development and life-cycles of cities. I also came to see the importance of our connection with the environment after living among the amazing nature on the Mediterranean island of Mallorca.
These experiences have developed my fascination with the interaction between cities and nature and how they fit together. As I am passionate about doing good for the Earth, I believe in making our cities more liveable for their inhabitants by pursuing more sustainable connections with our planet.
This connection I try to play out every day in my personal life. I am a doer and a creator. You will find me outside and doing something every month of the year with my hobbies: biking, camping, sailing, cross-country skiing, hiking. And when I am not doing one of those, I am creating, whether it be cooking in the kitchen, gardening in my yard, photographing around the city, or making maps using GIS.
GIS is at the crossroads of all of my interests and passions: the city, nature, and creating something. I love the visual aspect of maps and the stories that they tell. I hope to be able to make a difference in the world through the use of GIS, and I look forward to being able to bring all of my interests together in my career!

One of my main free-time activities is Photography. It originally started as a way to document my travels, but after taking a few classes I now work more from an artistic viewpoint.
I especially enjoy caputuring the contrast between the urban and natural worlds. I think this is a reflection of my comfort and enjoyment being in both environments.
My photos have won various local and international awards including a 1st Place in the "Cities and Nature" category of the Nature Conservancy 2017 competition and a 2nd Place in the "Greening the City" category of the International Garden Photographer of the Year 2018 competition.
See some of my work at the link below:
PhotographyI enjoy traveling and learning languages, and spent four years living in Europe.
I speak Spanish, Catalan, and German fluently from my time abroad and have also spent time learning Dutch, Swedish, and French.
Most days I would rather be outside than in and have many hobbies which get me outdoors. I am an avid user of my bicycle, both for in-city transportation and commuting as well as for longer day or overnight trips.
In summer I get out on Lake Michigan sailing or kayaking, and in winter I enjoy taking advantage of the snow to do exploring on cross-country skis.
Additionally, my photography is often a catalyst for seeking out the every-changing variences in Chicago's weather conditions, and I have developed a strong working knowledge of local weather patterns, which I put to good use planning all of my activities.
Volunteering is a way that I can explore various interests while helping improve the community in Chicago. The following are a snapshot of the activities I participate or have participated in:

THE OPPOSITE OF SEX A film review by Steve Rhodes Copyright 1998 Steve Rhodes
RATING (0 TO ****): ***
"I've never tried Communism, but I know I wouldn't like it," the brainless hunk, Matt Mateo (Ivan Sergei), tells Dedee, the teenage seductress who wants him to try sex with her. "Or grits," he adds after he thinks for a moment longer.
Dedee, the 16-year-old, seductive protagonist of the acerbic comedy, THE OPPOSITE OF SEX, has been coming on to Matt.
As Dedee Truitt, Christina Ricci from THE ICE STORM plays a role that is tailor-made for her sarcastic brand of humor. With in-your-face cleavage, short skirts, heavy make-up and platform shoes, she's a catty Lolita on steroids. Derided as "the human tabloid" for her proclivity for sleeping around, she is also the movie's sardonic, take-charge narrator. ("This is the part where I take the gun. Duh, this is, like, important.") As the narrator, Dedee manipulates the story by offering alternative versions and different perspectives on the story, which further enlivens an already exuberant picture.
Writer and director Don Roos's irreverent script can and should be compared favorably to Warren Beatty's BULWORTH. Happy to offend any group without worrying about retribution, this very funny picture dishes out one guffaw after another with many of the best lines being so raunchy as to be unprintable.
 She and Ricci share equally in the script's best dialog snippets.
"I'm bisexual," Matt announces after he finds he has impregnated Dedee. "Puh-lease!"  "I went to a Bar Mitzvah once. That doesn't mean I'm Jewish."
"This is how we do it on the Planet Maturia," Lucia lectures the clueless and immature Matt in another scene. "We have much to teach you."
The good-hearted story has Dedee and Matt disappearing. Bill, a teacher who has been falsely accused of molesting one of his former pupils, joins forces with Lucia in chasing after them. Among the many subplots is one involving the stolen ashes of Lucia's brother, to whom Dedee always refers mockingly as "Tom, the dead guy."
Lyle Lovett plays the good old boy, Sheriff Carl Tippett, who eventually beds Lucia. "What's the point of sleeping with you, Lucia, if it doesn't get your attention," he complains when she starts ignoring him.
The press kit offers widely varying interpretations of the film's provocative title, but Dedee offers the most intriguing explanation. "Sex always ends in, like, kids or disease or relationships." She says that this is just the opposite of what she wants.
THE OPPOSITE OF SEX runs 1:40. It is rated R for profanity and sexuality and would be fine for older teenagers.

Flexbox promises to save us from the evils of plain CSS (like vertical alignment).
Well, Flexbox does deliver on that goal. But mastering its new mental model can be challenging.
So let’s take an animated look at how Flexbox works, so we can use it to build better layouts.
Flexbox’s underlying principle is to make layouts flexible and intuitive.
To accomplish this, it lets containers decide for themselves how to evenly distribute their children — including their size and the space between them.
This all sounds good in principle. But let’s see what it looks like in practice.
In this article, we’ll dive into the 5 most common Flexbox properties. We’ll explore what they do, how you can use them, and what their results will actually look like.
Property #1: Display: Flex
Here’s our example webpage:
You have four colored divs of various sizes, held within a grey container div. As of now, each div has defaulted to . Each square thus takes up the full width of its line.
In order to get started with Flexbox, you need to make your container into a flex container. This is as easy as:
1 2 3 |
|
Not a lot has changed — your divs are displayed inline now, but that’s about it. But behind the scenes, you’ve done something powerful. You gave your squares something called a flex context.
You can now start to position them within that context, with far less difficulty than traditional CSS.
Property #2: Flex Direction
A Flexbox container has two axes: a main axis and a cross axis, which default to looking like this:
By default, items are arranged along the main axis, from left to right. This
is why your squares defaulted to a horizontal line once you applied display: flex
.
flex-direction
, however, let’s you rotate the main axis.
1 2 3 4 |
|
There’s an important distinction to make here: flex-direction: column
doesn’t align the squares on the
cross axis instead of the main axis. It makes the main axis itself go from
horizontal to vertical.
There are a couple of other options for flex-direction, as well: row-reverse and column-reverse.
Property #3: Justify Content
Justify-content controls how you align items on the main axis.
Here, you’ll dive a bit deeper into the main/cross axis distinction. First, let’s go back to flex-direction: row.
1 2 3 4 |
|
You have five commands at your disposal to use justify-content:
- Flex-start
- Flex-end
- Center
- Space-between
- Space-around
Space-around and space-between are the least intuitive. Space-between gives equal space between each square, but not between it and the container.
Space-around puts an equal cushion of space on either side of the square — which means the space between the outermost squares and the container is half as much as the space between two squares (each square contributing a non-overlapping equal amount of margin, thus doubling the space).
A final note: remember that justify-content works along the main-axis, and flex-direction switches the main-axis. This will be important as you move to…
Property #4: Align Items
If you ‘get’ justify-content, align-items will be a breeze.
As justify-content works along the main axis, align-items applies to the cross axis.
Let’s reset our flex-direction to row, so our axes look the same as the above image.
Then, let’s dive into the align-items commands.
- flex-start
- flex-end
- center
- stretch
- baseline
The first three are exactly the same as justify-content, so nothing too fancy here.
The next two are a bit different, however.
You have stretch, in which the items take up the entirety of the cross-axis, and baseline, in which the bottom of the paragraph tags are aligned.
(Note that for , I had to set the height of the squares to auto. Otherwise the height property would override the stretch.)
For baseline, be aware that if you take away the paragraph tags, it aligns the bottom of the squares instead, like so:
To demonstrate the main and cross axes better, let’s combine justify-content and align-items and see how centering works different for the two flex-direction commands:
With row, the squares are set up along a horizontal main axis. With column, they fall along a vertical main axis.
Even if the squares are centered both vertically and horizontally in both cases, the two are not interchangeable!
Property #5: Align Self
Align-self allows you to manually manipulate the alignment of one particular element.
It’s basically overriding align-items for one square. All the properties are the same, though it defaults to auto, in which it follows the align-items of the container.
1 2 3 4 5 6 7 8 |
|
Let’s see what this looks like. You’ll apply align-self to two squares, and
for the rest apply align-items: center
and flex-direction: row
.
Conclusion
Even though we’ve just scratched the surface of Flexbox, these commands should be enough for you to handle most basic alignments — and to vertically align to your heart’s content.
